Pseudo 1.7 adds an experimental feature (which I think needs more testing before it becomes the default) allowing the pseudo client to store modes and uid/gid values in extended attributes rather than using the sqlite database. On most Linux-like systems, this works only if the underlying file is a plain file or a directory. Also added is a profiling feature to allow some amount of reporting on the wall-clock time the client spends in wrappers, processing operations, or in IPC. This feature is not intendeded to be precisely accurate, but gives a good overview of where time is going. Based on the results from the profiling feature, the client now suppresses OP_OPEN and OP_EXEC messages if the server is not logging messages, and no longer uses constant dynamic allocation and free cycles for canonicalized paths. There's a few other likely-looking optimizations being considered, but this seemed like a good cutoff for now. 1.7.1 fixes two bugs, one affecting mostly XFS systems with 64-bit inode values, and one affecting code that called realpath(x, NULL), such as the RPM backend. 1.7.2 fixes an indirect side-effect of the chmod fixes to deal with umask 0700, which had no effect with opkg 0.2.4 but appears to cause failures with 0.3.0. 1.7.3 prevents mkdirat() (and mkfifoat()) from setting errno on success, because glibc's localedef inexplicably errors out if errno was set, even if the operation's actual return code (which it tests) indicated success.

Poky
Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
bitbake: Git repository: http://git.openembedded.org/bitbake/ Mailing list: bitbake-devel@lists.openembedded.org
documentation: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/ Mailing list: yocto@yoctoproject.org
meta-yocto(-bsp): Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp) Mailing list: poky@yoctoproject.org
Everything else should be sent to the OpenEmbedded Core mailing list. If in doubt, check the oe-core git repository for the content you intend to modify. Before sending, be sure the patches apply cleanly to the current oe-core git repository.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix of oe-core and poky-specific files.
